Aryabhatta I, born 476 A.D in Patliputra in Magadha is now modern Patnain Bihar. There are several tales of claim for his origins. Many believe that he was born in the south of India around the Kerala region and lived in Magadha at the time of the Gupta rulers; time which is known as the golden age of India. There is no evidence that he was born outside Patliputra and traveled to Magadha, the centre of instruction, culture and knowledge for his studies where he even set up a coaching institute. His first name "Arya" is not a south Indian name while "Bhatt" (or sometimes Bhatta) is a typical north Indian name. The name is popular even today in India especially among the trader community of north India.

Pataliputra was the birth-place of another very great man, namely, Aryabhata, the father of scientific astronomy and mathematics of the Hindus. He was born in 476 A D. and wrote his Kala-kriya (calculation of time) here at the age of 23 that is, 499 A.D.
